GGMBINED INTAKE AND DISCHARGE VALVE.

Application filed September 18, 1924. Serial No. 73%,5 25.

Toizll whom it may m Be it known that I, THOMAS BOVEY, a citizen of theUnited States, and a resident of Chicago, in the county of Cook andState such as will enable others skilled in the art to make and use thesame.

. "My present invention relates to a valve for use in conjunction withan automobile heater, the construction of which valve is such that whenthe valve-plate is in normal position it permits of the continuedstraight-away flow of the hotv gases from the exhaust maniiold to.themufiler, but when the valve-plate is moved to a transverse position'forat substantially a rightangle to its normal position, the valve casingwill take in hot gas from the exhaust pipe and direct the same to aconduit or pipe leading to the heating radiator within the vehicle, andthe same valve and casing will permit the return of the exhaust from theoutlet of the heater back into }the exhaust pipe. Thus there is acontinuous and uninterrupted 'fiow of the hot gas in which ever positionthe valve plate may be positioned.

One of the objects of my invention is to provide a valve within whichthere is provided a web or wall that extends from between the dischargeand return stubs into the central portion of the casing'where it turnsdownwardly to a point about mediate theends of the valve opening or seatat the bottom of the casing so that it will be unnecessary to provide aspecially co. structed and positive seat for the valve W 'en in atransverse or open position while the heater is in use.

In my prior application, filed Aprll 5th, 1923, Serial No. 629,987 for avalve for'automobile heaters, I have disclosed a valve of a type similarto the valve herein de-' scribed. In said prior structureit wasnecessary to form or machine a seat for the edge of the valve-plate sothat there'would be a snug fit when the plate is moved to a transverseposition in order to prevent the oppositely movingcurrents of hot gas1n-' terfering with each other. while the heater is in use. This type ofstructure is expensive from a manufacturin standpoint because itrequires the use 0 special tools to mill or machine out an arched seatdeep in the casing. I have, in mypresent design of valve, provided acasing in which the web or dividing wall, which provides the inlet andreturn passageways, extends down to thelocation of the valve-spindle orstein so that it is unnecessary to mill. or machine a seat for the edgeof the valve-plate, as before mentioned.

It is a further object of my invention to provide a valve andvalve-casing that is simple in construction and dependable in operationand which is novel in the arrangement of its parts. All the foregoingobjects I prefer to accomplish in the manner substantiallyas'hereinafter described and as more particularly pointed out in theappended claims, reference being had to the drawings accompanying thisspecification Figure 2 is a transverse vertical section 8i? thereof online 2-2 of Figure 1.

Figure 3 is a central longitudinal section of the structure illustratedin Figure l.

The drawings illustrate a typical or preferred embodiment of myinvention, and in $5 said drawings I have designated similar parts bymeans of the same reference characters wherever said parts occurthroughout the several views. The structure preferably" comprises acasting 5 that is hollow, and extending obliquely upwardly from theupper portion of the same is a discharge-stub 6, and disposed withits'axis parailel with the aforesaid stub 6 is a return-stub '3 thatleads into the casting for the return of the exhaust gas thereto. Thesestubs are adapted to recive len the of flexible metallic hose or conduit0 a length suficient to convey the exhaust gas between valve casing andthe proper ports in the radiator of the heater structure that is usuallydis posed on the floor of the vehicle. The radiator, the housingtherefor, and. -;the flexible pipes, may be of any suitable or wellknown construction and, therefore, need not be a herein disclosed.

Extending in from the edge of the easing and in a plane betweentheparallel axes to divide the interior of the latter into two passageways,9 and 10, one" of which (9) extends directly out of the casting and theother (10) extends parallelthereto and then turns downwardly past theadjacent end of the first passageway so that said passageways terminatealongside .each other at their outer or lower ends. I

The bottom of the casting or housing is provided with a longitudinallyeelongated opening 11, which is of substantially the same extent as thecombined cross-sectional area of'the two passageways and said open ing11 is substantially intersected by the adjacent end portion of the wallor web 8.

The casing on its bottom is provided with a: basal member 12 which maybe of any suitable shape so as to be conveniently secured to the exhaustconduit or i e that leads from the engine to the mu er. In

the present instance I have shown the basal member arched or concavedupwardly so as to partially surround the cylindrical pipe or embossmentand it'is provided with suit-l able means for securing the same" inplace. In installing the structure just described a longitudinalelongated aperture l3-is made in the exhaust pipe 1%, of sufiicientwidth and length to accommodate the movement of the valve-plate, tobe-liereinafter de scribed, so that when the arched portion-of the basalmember 12 is littedupon the pipe,

14 this aperture l3 will be in registry with the opening 11 formediiithe casing.

The valve comprises an elongated plate 15 having its ends rounded intosemi-circa lar shape so as to snugly fit the aperturell, which ispreferably correspondingly shaped in the bottom of the valve casing andsaid plate is mounted upon a rotatable spindle 16 that-is journaled inthe hearings in the opposite side walls of the casing so as to bepositioned transversely of the opening at about the lower end of thedividing wall or web 8. A bell crank lever isniounted 'upon one of theextended ends of the'spindle and has its longer arm 1? f of an open. rodextends" into the vehicle to within convenient reach of the occupants.The other or shorter arm 18 0f the bell crank has a coiled contraction19 connected to it, and the opposite end of said sprin is sccin'ed uponthe laterally bent end 20 of rod 21 mounted in a suitable boss 92 formedon exterior wall of the casing. This spr g normally maintains the valvein a closed seat in the aperture ll of the 131 When, however the valveis opened by a longitudinal movement of the rod ill the plate 15 will bemoved with its spindle 16 to a position transverse of the opening oraperture ii and with its upper portionalongside the lateral port-ion or"well or'web 8 while its lower portion extend nn'ected to one endposition upon its me ial through the aperture 13 in the exhaust ipe tointerlit with the lower half thereo so as to interrupt the continuousstraight-away fiowor" the exhaust gas. -This will dlrect said gas upinto the valve casing and into which returns it to the exhaust pipe 14through passageway 9 uponfthe opposite side of the valve plate, asindicated by ar rows in Figure 3 ofthe drawings.
